Real-time collisions of fractional charges in a trapped-ion Jackiw-Rebbi field theory
Alan Kahan, Pablo Viñas, Torsten V. Zache +1
We propose and analyze a trapped-ion quantum simulator of the Jackiw-Rebbi model, a paradigmatic quantum field theory in (1+1) dimensions where solitonic excitations of a scalar fi…
A higher-order topological twist on cold-atom SO(5) Dirac fields
A. Bermudez, D. González-Cuadra, S. Hands
Ultracold Fermi gases of spin-3/2 atoms provide a clean platform to realise SO(5) models of 4-Fermi interactions in the laboratory. By confining the atoms in a two-dimensional Rama…
Large- and tensor-network methods for strongly-interacting topological insulators
E. Tirrito, S. Hands, A. Bermudez
The study of correlation effects in topological phases of matter can benefit from a multidisciplinary approach that combines techniques drawn from condensed matter, high-energy phy…
Correlated Chern insulators in two-dimensional Raman lattices: a cold-atom regularization of strongly-coupled four-Fermi field theories
L. Ziegler, E. Tirrito, M. Lewenstein +2
We show that ultra-cold atoms with synthetic spin-orbit coupling in Raman lattices can be used as versatile quantum simulators to explore the connections between correlated Chern i…
Floquet-engineered vibrational dynamics in a two-dimensional array of trapped ions
Philip Kiefer, Frederick Hakelberg, Matthias Wittemer +4
We demonstrate Floquet engineering in a basic yet scalable 2D architecture of individually trapped and controlled ions. Local parametric modulations of detuned trapping potentials…
Dirac-Weyl fermions with arbitrary spin in two-dimensional optical superlattices
Z. Lan, N. Goldman, A. Bermudez +2
Dirac-Weyl fermions are massless relativistic particles with a well-defined helicity which arise in the context of high-energy physics. Here we propose a quantum simulation of thes…
